Syntax error: %s PARTITIONING requires definition of
MySQL raises "Syntax error: %s PARTITIONING requires definition of VALUES %s for each partition" when a CREATE TABLE or ALTER TABLE statement declares partitioning without mandatory value boundaries.
The parser requires every RANGE or LIST partition to include a VALUES LESS THAN(...) or VALUES IN(...) clause so it can route incoming rows correctly.
Until each partition lists its boundary, the DDL statement is rejected, leaving the table uncreated or unmodified.
Leaving out VALUES LESS THAN for RANGE partition definitions triggers the error immediately.
LIST partitioning fails when VALUES IN(...) lists are missing, empty, or contain syntax mistakes such as trailing commas.
Copying partition templates from other databases without adapting them to MySQL's exact syntax also leads to error 1479.
Add a VALUES clause to every partition definition. RANGE partitions need VALUES LESS THAN, and LIST partitions need VALUES IN.
Verify that boundaries are mutually exclusive and in ascending order for RANGE partitions to prevent secondary errors.
Run the corrected statement in Galaxy's SQL editor to confirm the table now creates successfully.
Creating a date-based RANGE partition without VALUES LESS THAN results in error 1479. Add VALUES LESS THAN ('2024-01-01').
Bulk generating LIST partitions for status codes but forgetting VALUES IN(1,2,3) yields the same error. Supply the missing code list.
Using ALTER TABLE ... ADD PARTITION without providing VALUES also triggers the error; include the VALUES clause in the ADD PARTITION syntax.
Template partition definitions with placeholders for VALUES so they are never omitted during copy-paste.
Use Galaxy's AI copilot to auto-fill boundary clauses and validate partition SQL before running.
Add unit tests that execute SHOW CREATE TABLE to verify each partition carries the expected VALUES clause after migrations.
Error 1480 ER_PARTITION_WRONG_VALUES triggers when VALUES clauses overlap; review boundaries for duplication.
Error 1493 ER_PARTITION_CONST_DOMAIN_ERROR occurs when VALUES use non-constant expressions; replace with literals.
The partition definition omits VALUES LESS THAN or VALUES IN, leaving MySQL without routing information.
A LIST partition includes VALUES IN() with no actual values, which the parser treats as missing.
RANGE partitions list VALUES LESS THAN out of ascending order, confusing the optimizer and triggering a syntax failure.
Extra commas, parentheses, or keyword misspellings disrupt the VALUES syntax and raise error 1479.
Raised when VALUES boundaries overlap or are duplicated across partitions.
Occurs when non-constant expressions appear in a VALUES clause for LIST or RANGE partitions.
Thrown if a partition key uses an unsupported function or data type.
No. HASH and KEY partitions do not need VALUES clauses, so this error is exclusive to RANGE and LIST types.
No. The clause must contain constant literals. Using functions triggers ER_PARTITION_CONST_DOMAIN_ERROR.
Yes. Galaxy's linter flags incomplete partition definitions and suggests the proper VALUES syntax before execution.
From MySQL 5.7 onward, ALTER TABLE ... ADD PARTITION is online for InnoDB, so applying fixes usually avoids downtime.
